Hi,
Since Fred's part was 56 cm, his sister's was 84-56=28
She cut it into 4 parts, so 28/4=7 cm
Her rope was 7 cm long.
Hope this helps you.
2 3/4. Three halves and four make five and a half. Two fourths is the same as a half . You want half of five and a half which is two and three quarters.
Answer:
angle 1 should equal to 54.
angle 2 should equal to 126.
Step-by-step explanation:
2x - 8 + 4x + 2 = 180
2x + 4x - 8 + 2 = 180
6x - 6 = 180
6x - 6 + 6 = 180 + 6
6x = 186
6x ÷ 6 = 186 ÷ 6
x = 31
---------------------------------------------
2x - 8 = A1
2(31) - 8 = A1
62 - 8 = A1
54 = A1
-----------------------------------------------
4x + 2 = A2
4(31) + 2 = A2
124 + 2 = A2
126 = A2
